1. larger engine size

This measurement is the total volume of all the engine's cylinders, also known as the engine displacement. This is one of many aspects of an engine that determine its horsepower, but generally speaking a greater size indicates more power.

2. better fuel economy (combined)

Fuel economy is a measurement of fuel efficiency, based on how far you can travel with a certain amount of petrol (gasoline). A lower fuel economy means the car will be cheaper to run.

3. more horsepower

Horsepower is the most common unit for measuring the power of an engine.

435hp

Hennessey Venom GT (2014): 1244hp

200hp

170hp

4. longer wheelbase

The wheelbase is the distance between the center of the front and rear wheels. A longer wheelbase provides the car with more stability and a smoother ride (although a shorter wheelbase can provide more responsive handling).

5. Has a petrol (gasoline) engine

A petrol (gasoline) engine offers several advantages over diesel. For example the engines tend to be lighter and cheaper than their diesel counterparts. Petrol engines also tend to have higher horsepower, and the fuel is more readily available.

12. Has air suspension

Air suspension offers a smoother ride than the traditional steel spring suspension. It is also often adjustable, allowing you to raise or lower it based on the type of driving you are doing.

15. higher maximum torque

Torque is a measurement of an engine’s power, closely related to horsepower. More torque indicates a more powerful car, and is also a good indication of its acceleration.

21. Has rear-wheel drive

Rear-wheel drive benefits from increased traction when accelerating, as the weight of the vehicle shifts to the rear over the drive wheels. The weight of the car is also more evenly distributed, resulting in improved handling.

24. Has a turbocharged engine

A turbocharger compresses the air entering the cylinders, allowing more air (and therefore more fuel) to be added - resulting in a more powerful explosion. This leads to an increase in horsepower without increasing the size and weight of the engine.
